This is the normal western type of C. fieldii; the latter is 
represented by a species near to C’. aurorina, which, though found in 
the west, extends as far eastward as Assam ; whether the two forms 
are distinct or not can only be decided by breeding. Of course the 
present form is generally called C. fieldit in Indian collections ; ; but 
if it be that species, it should stand as var. edusina.

One male of typical C. erate was obtained at Murree on the same 
day as the male of var. pallida ; Major Yerbury says that it does 
not appear to be so common at Murree as the latter; a second 
fragmentary male from Campbellpore was also sent with specimens 
of C. pallida. Both Col. Swinhoe and Mr. de Nicéville seem to have 
wrongly identified the form, though, as C. sareptensis was mixed up 
with it, I may be mistaken in the case of the former gentleman: 
Major Yerbury, however, quotes the Tages as ‘‘ Colias hyale apud 
de Nicéville, C. sareptensis apud Swinhoe”’ ; he says that at Murree 
it is not common. He further remarks as follows :—* When first I 
arrived in Campbellpore and began to collect, I had no setting-
